In theconstruction of the typical embodiment of 'they improved device as shown in theY drawings;

'the numeral I5 designates a base plate or. table Whereonthe other elementsv ofthe assembly aremounted, grouped, positioned, and operatively associated. The table( I5, of any shape or sizev conveniently suitedto its purpose, is.of hard, rigid materialgsuch as metal, hasa plane,` smooth, up-

A straight groove, shallow inrelation'to its width, centrally intersects the table I5 upper surface in traversing relation between the/table upper andV lower margins to slidably seat and reciprocably accommodate a straight; rigid actuating member.

I6 ofA alength somewhatless than thatV of'said groove, and suitable stops II and I8: are xed to the ,table I5 l in obstructing relation across the op,- positeends of said groove to positively limit the range., Qfmember l'reciprocatory navet-therein.

Ade' jacent and beneath the lower end ofjthe `member I5, a slot 22, elongated in the direction of said member reciprocation, opens Ythrough the concern as to the specific means and agencies employed for the purpose, wire stock material 33 is fed in continuing supply downwardly across the upper marginof the. table I5, against the upper inclined plane face of said table in spaced parallelism with the member I6, and into the upper end of the straight feedway defined by the progressively-arranged stations on the corresponding side of said member. At the upper end o fueach feedway,rthe wire 33 traverses and feeds through a pair of functionally-similar, succes- Y! sively-arranged, complementary stations reactive table I5 and floor of said member groove or slide- I way in registration with a relatively shorter aperture 23 intersecting said member lower end, and `lugs 24 fixedly depend from the table I5 under surface on opposite sides of said slot 22 to support a transverse hinge member 25 whereon a lever 26 is mounted for oscillation in a vertical plane longitudinally intersecting the member I5. The upper end of the lever 26 is formed with a transversely-cylindrical head 21 engaging within and to operatively bear against upper and lower margins of the aperture 23, and the lowerl end of said lever is hingedly connected with the free end of the piston stem 2l so that, the effective lengths and operative dispositions of the pertinent elements being properly proportioned, extension and retraction of the stem 2I relative to its cylinder is reflected as proportional, oppositely-direeted reciprocation of the member I6 relative to the table I5. Automatically-controlled, cyclic, power actuation of the piston and cylinder unit is vconveniently had through the agency of a reversible pressure'flow control valve assembly 28 fixed to the table I5 under side beneath the upper end of the member I6 with its shiftable, flow-reversing element operatively linked, as at 29, to a lug 3D iixedly depending from the member I6 upper end through a slot in the table I5 disposed for operative accommoda` tion thereof. The valve assembly 28 is served by a pressure flow line 3I, leading from any'convenient source or supply of fluid under pressure, and pressure flow lines 32 connect the alternative pressure flow outlets of said assembly 28 with the opposite ends of the cylinder 20, thev to member I6 reciprocation with straightening effect on the wire portions engaged thereby, the first of said stations comprising a rigid arm 34 hinged intermediate its ends to a bracket 35 upstanding from the table I5 face between the feedway and member I6 upper end and thus disposed for oscillation in a plane perpendicular to the table face and to the member I6 travel path with its' inner end overhanging the member I6 upper'jend and its outer end overhanging the feedway, and a shoe 36 elongated in a direction perpendicular to the arm 34 hingedly depends from said arm outer end with its under surface in spaced, parallel opposition to the table I5 surface constituting the upper feedway portion. The arm 34 inner end is resiliently urged and held toward the adjacent member I6 upper suring engagement with and against the upwardly- 35" the shoe 3b under surface toward the cooperatoperative arrangements and adjustments of the' pressure responsive and control elements being such as to reverse pressure flow to the cylinder 26 at each limit of member I6 reciprocation and thereby maintain cyclic power actuation of said y member as long as fluid flow at adequate presi sure is available through the line 3 I.

The member I6 cooperates with and actuates a plurality of stations operatively disposed along and to define a feedway for stock material spacedly paralleling each side of said member, the feedways and associated stations on the opposite sides, of said member being functionally identical and structurally similar with only such differences of element form, disposition, and relative spacing as are requisite to adapt the operating line of a given feedway to the formation of a particular hook size from suitably-proportioned stock material; detailed description of but one of said lines hence being adequate for an understanding of both.

The stock material from which the hooks are formed is readily-workable annealed or soft metal wire of selected gauge suited to the type and size of hook to be made, which wire is com-V monly supplied in coils, on spools or reels, or in bundled straight lengths. Regardless of the particular form in Which'supplied and without "ing table I5 surface, with straightening effect in one direction on the wire 33 engaged therebetween', when the member I6 is at the upper limit of its range of reciprocation, and to permit Adepression of said arm inner end toward the Vmember I6 through the agency of the spring 31,

with consequent increase of the spacing between the shoe 36 and table surface, when said member is at the lower limit of its reciprocation. rThe second of the wire-straightening stations is 50v`immediately below and in alignment with the station just described and is arranged for straightening effect on the wire in a direction perpendicular to that of the first station, wherefore said second station conveniently consists of 'an elongated abutment 39 fixedly upstanding from the table I5 on the outer side of the feedway and defining one side of the latter by means of its straight, long inner face paralleling the member I6, a shoe 40 reciprocable transversely 'of the table I5 between said member I6 and wpin', Aand spring arrangement shown in Figure 6, act on the finger 42 to urge said finger, with its associated shoe 4D, away from the abutment 39-and toward the member I6, thus maintaining the preferably-rounded finger inner end in slidable-engagement against the member I6 adjacent side margin and for extension at times aga-eases;

51 awa-yfrom the block 4I into seated: reception within a cam notch 43 inwardly intersecting the said member side margin. The notch 43 is so disposed along the member I6 and so related with the position of the nger 42 as to register with and receive the inner end of the latter, thereby opening the maximum feedway spacing between the abutment 39 and shoe, 40, when the member I5 is at the lower limit of its reciprocatory range, as shown in Figure l, and said notch is so shaped as to shiftr said finger outwardly through the guide-block 4Iv andv to thereby ap.- proach the shoe 46 toward and into minimum spaced relation with the abutment 39 when said member I6 is moved upwardly-2 away from itsv lowermost position; the shoes 36 and 4U hence simultaneously clamping with straightening ef'- fect and in perpendicularl'y-related directions against successively-adjacent sections of the wire 33 when the member I6l is ranging inthe upper reaches of its travel, and retracting out of said clamped adjustment to fully release the wire 33 for travel longitudinally of the feedway when said member is at the direction-reversing lower limit of its oscillatory cycle.

Immediately below the abutment 39 and on the outer side of the feedway, a block 44 is xed to and upstands from the table l5 surface to removably and replaceably mount and fixedly position a forming element 45 adjacent the path of wire 33 travel, and a guide-block 46 is fixed to said table I5 between the feedway and member I6 in spaced opposition with the block 44 to position and slidably accommodate a forming element 41 reciprocable transversely of the table I5 between the member I6 and element 45 ior end coaction at times with the latter. In -an arrangement similar to that of the ringer 42, the element 41 is spring-urged toward the member I6 for maximum separation of its outer end relative to the element 45 inner end, and the rounded inner end of said element 41 is thus slidably held against the member I6 side margin in position to register with and at times seat within a cam notch 43 intersecting the member i6 margin below the notch 43, the said notch 43 being so correlated with the member I6 length and element 41 location as to register with and receive said element inner end when said member reaches the lower limit of its oscillatory travel. Adjacent ends of the elements 45 and 41 are respectively formed as complementary female and male dies engageable against opposite sides of a wire 33 traversing the feedway therebetween and are so shaped as to define by their coaction a lateral, outwardly-displaced oiset 49 in the wire 33 portion thereby engaged, and adjacent corners of said elements 45 and 41 at the upper end of the said offset 49 are formed as complementary inclined shear jaws 56 coactable to sever the wire 33 at the upper crimp angle of the offset for positioning of the latter at and as the upper end of a separate stock section for subsequent forming into a hook-shank-terminating, closed eye and to initially point the leading end of the following section; it being obvious that upward travel of the member I6 from its Figure l disposition operates to shift the element 41 toward the element 45 with offset-forming and wire-severing response of the element die land jaw end portions.

Obstructing the feedway where it emerges from l between the blocks 44 and 46 downwardly of the table I5, a guide-block 5l, formed with a longitud-mal channel constituting an aligned continu- 6= ation. of the feedway and of sumcient.; widtht tp, pass. the. oiset 49 of a wire section, is,Y fixe te said table in covering relation with an anvil; 52- sunk into the table I5 across the feedwayv atl aL distance, below the jaws 56 corresponding to the` overall stock wire length of the hook to be formed. The upper surface of the anvil 52 is worked and contoured to function as a, wire-- pointing. die in cooperation with the lower end of a plunger 53 reciprocablein a guide-way through,

the block 5I lower end portion perpendicular te thetable I5, for which purpose the anvil 52 upper surface is coplanar at its upper margin withY they feedway iloor and thence arcuately diverges fromA the table I5 planer to elevated relation of, its lower margin with the feedway floor, While the plunger 53 lower end is eccentrically arched to substantially close at times against the anvil sur. face elevated lower margin and complete the definition of an arcuate throat Vdivergently opemA ing toward the upper reaches of the feedway; The` plunger 53 is formed on or associated for actuation with the outer end of an arm 54 trans-1v versels7 bridging between the block 5I and member I6 in hingedly mounted relation intermediate its ends with a bracket 55 xed to the table I5,L and the inner end of said arm 54 slidably rides over and along the upper contoured face of a cam block 56 suitably located on and fixed to the member I6, spring means of convenient type-, such as at 51, being arranged to yieldably holdthe arm 54 inner end against the cam surface of the block 56. The block 56 cam surface is SQ shaped as to react through the arm 54, as the member I6 is reciprocated, for elevation of theplunger 53 lower end away from the anvil 52 a distance suicient to freely pass a worked wire stock section therebetween and downwardly along the feedway when the member I6 is at the lower limit of its range of travel, to close the plunger 53 lower end in its nearest approach to the anvil 52, with point-forming eiTect on a stock wire end engaged therebetween, when said member is at the upper limit of its range of travel, and to dispose said plunger 53 lower end upwardly away from the coacting anvil surface a distance less than will pass the stock material, in which re.- lation said plunger and anvil function as a stop to limit stock material travel downwardly along the feedway, during the rest of the member oscillatory cycle. Opening through the upper end portion of: the block 5I in alignment with the feedway thereunder, a slideway inclines downwardly of and toward the table I5 to intersect the feedway just above the anvil 52 and plunger 53, and a chisel-type tool 58 is reciprocably mounted in said slideway with its operating end, directed toward the stock wire 33 in the feedway at the upper margin ofy said anvil. It is the function of the. tool 58 to cut and shape a barb on the stock wire in properly-spaced relation with the wire end pointed by the anvil 52 and plunger 53, and to that end the tool 58 projects outwardly from the block 5I and is linked to the outer end of a lever 59 disposed to swing in a plane parallel with the table l5 about a fixed pivot perpendicular to said table betweenA the tool 58 and the member I9. The inner end of the lever 59 overhangs the member I6 between the cam block 56 and notch 48 in position to be alternately engaged and oppositely moved by an. abutment 50 xedly upstanding from said member adjacent the cam block 53 and a pin or stud 6I xedly upstanding from said member adjacent. the notch 48 in upwardly-spaced relationwith Said abutment, the disposition of .the abutment 60 and stud 6I on the member I6 being so adjusted' to the lever 59 position and the oscillatory cycle of said member as to actuate said arm for workeiecting engagement of the tool 58 chisel end against the stock material in the feedway when the member IB is at the upper limit of its cyclic.

Va block 63 iixed to the table I5 in covering relation with the feedway and at one side of thel member I5. The feedway-deiining channel through the block 63 is straight and unobstructed for the major portion of its length and Y is formed with a shoulder 64 adjacent its lower end outstanding from the channel side wall remote from the member I6 and directed toward said member in position to be engaged by the lower crimp of the offset 49 formed on a stock wire section slidably traversing the feedway,

which engagement serves to check the travel of and to position said section relative to forming agencies adapted to act thereon. A slideway through the lower portion ofthe block -63 perpendicular to the feedway reciprocably accommodates a die element 65 between the shoulder 64 and member I6 and for coaction with said shoulder in the clamping of a stock wire section shank therebetween, corresponding upper corners of said shoulder and die element outer endbeing arcuately worked to denne an upwardlydirected forniing recess. The element 65 is resiliently urged, as by means of a spring GG, in a direction to separate its outer end from the shoulder 64 and to maintain its rounded inner end slidably against the adjacent member I6 side margin, and said member side margin is formed with a cam notch 61 disposed to register with and seat the element 65 inner end, and thereby opening the feedway between the shoulder v64 and element outer end for free passage of a stock wire section downwardly past said shoulder, when said member I6 is at the lower limit of its reciprocation. A laterally-offset forming. tool 68 is slidably accommodated in the block 63 for longitudinal reciprocation, in a vjogged path generally parallel to the feedway, between` feedway-obstructing disposition of its lower end in opposition to the recess formed by the shoulder 64 and element 55 upper corners and lateral. displacement in clearing relation with said feedway, and the lower end of said tool'63 is worked as a downwardly-directed, semi-circular recess above a wedge-shaped shoe cooperating with the feedway floor, so that, a stock wire section formed with an offset 49 being clamped between4 the shoulder 64 and element 65, travel of the toolj 68 downwardly of its mounting in the block 63 acts through its end recess and shoe to form the section offset 49 into a closed loop eye on the section upper end and to bend the so-formed eye: into elevated relation of its upper margin awayA from the feedway floor and into consequent angular relation with the hook shank. Automa-r4 tic, synchronized. actuationv of the.V 1:00168 mit means of the member I6 is effected through a lever 69 swingable in a plane parallel to the table I5 about a pivot perpendicular to and fixedly upstanding from said table adjacent the block 63 upper end, the end of said lever outwardly beyond said pivot operatively connecting with the tool 68 upper end and the portion of the lever inwardly of the pivot overhanging the member I6 between spaced posts 10 iixedly upstanding from said member in position to alternately engage against opposite sides of the lever as said member is reciprocated, the upper of the posts 10 functioning through the lever 69 to withdraw the tool 68 relative to the block 63 and out of obstructing relation with the feedway as the member I6 approaches its lower reciprocatory limit and the lower of said posts functioning to swing said lever for eye-forming actuation of the tool 68 as said member approaches the upper o its oscillatory limits.

Just below the block 63, complementary abutments 1I and 12 rise from xed relation with the table I5 to define outer and inner sides, respectively, of the feedway continuation and to mount hook-shaping means in operative association with a stock wire section held between the shoulder 6d and element 65 of the assembly. The abutment i2 slidably accommodates a stein 13 between the feedway and member I6 for projection of its outer end at times across and above the feedway and the shank of a stock wire section therein, and said stem 13, yieldably spring-urged toward the member I6, is formed with a rounded inner end overlying the member I6 margin for slidable cooperation with the notched margin of a cam block 14 carried by said member. The block 14 and the marginal notch 15 thereof are so correlated with their associated elements as to permit seated registration of the stem 13 inner end within said notch 15, and consequent retraction of the stem outer end out of obstructing relation with the feedway, when the member I6 is at the lower limit of its reciprocation, and to hold said stem with its outer end intersecting said feedway during the rest of the actuating member cycle, and said stem outer end is formed as a head 16, marginally worked to conform with the inner outline of the desired hook bight, about which the stock wire section is bent and fitted to ultimate finished shape. In its operative position, the head 16 preferably end-closes against the face of the abutment 1I as a mandrel fully obstructing the upward passage between the adjacent abutment 1I and 12 faces and in position -1 for cooperation with an arcuate shaping ringer 11 actuatable to roll and form the hitherto straight lower portion of the stock wire section thereabout. The iinger 11 is operatively housed within a slot in the table I5 intersecting the feedway below and downwardly of the table from the working position of the head 16, and is arranged for oscillation about a shiftable pivot 18 mounted in the table I5 below the floor and in a direction perpendicular to the length of the feedway, said pivot 18 being so associated with and mounted-in said table as to have limited scope for displacement of its axis in a plane parallel to the table surface and in a direction parallel to the feedway. The free, working end of the iinger 11 is adapted to move about the pivot 18 from full retraction within the table slot, where it closely underlies the feedway iloor downward extension, through an upwardly-directed arc to coaction with the 4sdenof the head I6 remote fromme. bmclslrandltamt andqbend the Stock,

wire section free lower portion overlying said ringer against 'and about sa'idhead as anincide'nt of such motion, to which end fthe nger free tip isrounded and merged smoothly with arconcavity polishing or coating. As the member I6 is poweriactuated, -a straight feedway paralleling said member is 'fully opened and cleared ofrall obstruction to gravity-induced travel of stock material 'in the nger upper margin .contoured .to .co'act 5 sections therealong when Isaid member 'is at the with and `clamp the stock wire 'sectionaga'inst'the head le when said finger attains the'limit of its work stroke.
